TRANSCRIPTION DNA – RNA – Protein
2
Types of RNA Messenger RNA (mRNA) - is a copy of a portion of the original DNA strand carries the RNA copy of the DNA code for one or more genes in a series of codons; one codon codes for one amino acid Ribosomal RNA (rRNA) - made of 2 subunits work together to make ribosome that is capable of reading mRNA from 5’ to 3’ and assembling amino acids to make protein Transfer RNA (tRNA) - capable of attaching to an amino acid at top near the acceptor stem; at bottom has anticodon loop that is the compliment of the codon found on mRNA
